EXSUM                                                      Calendar Year 2019 DoDSER Annual Report

                                    Executive Summary
The Department of Defense Suicide Event Report (DoDSER) is the official reporting system for
deaths by suicide and suicide attempts among Service members in the U.S. Air Force, Army,
Marine Corps, Navy, and Space Force. The DoDSER Annual Report presents aggregated results
generated from the DoDSER data collected by the Military Services during a specified calendar
year. New for this year, the Calendar Year 2019 (CY19) DoDSER Annual Report also contains
information in response to Section 741 of the National Defense Authorization Act (NDAA) for
Fiscal Year 2020 (FY20), “Reports on Suicide among Members of the Armed Forces and
Suicide Prevention Programs and Activities of the Department of Defense.” Section 741 required
the Secretary of Defense to report on the total number of suicides, attempted suicides, and known
cases of suicidal ideation among service members (including the reserve component) during a
specified year; the number that occurred during the first 180 days of service along with the
associated initial recruit training locations; and the number that occurred during a contingency
operation deployment. The CY19 DoDSER Annual Report meets the requirements of Section
741 as described in Appendix A, “Section 741 NDAA FY20 Reporting Requirements.”

CY19 Suicide Mortality Rates
There were 344 deaths by suicide identified among active-component service members. The
suicide mortality rate was 25.9 deaths per 100,000 population.

The suicide mortality rates for each active-component service were as follows:

           •   Air Force: 25.1 suicides per 100,000 population
           •   Army: 29.8 suicides per 100,000 population
           •   Marine Corps: 25.3 suicides per 100,000 population
           •   Navy: 21.5 suicides per 100,000 population
           •   Space Force: 0 suicides per 100,000 population (from establishment of Space
               Force on December 20, 2019 through December 31, 2019)

The suicide mortality rates for the Reserve and the National Guard were 18.2 and 20.3 suicides
per 100,000, respectively.

Military Suicide Mortality Rates over Time
For the active-component population, the data indicated a per-year increase in the suicide
mortality rate ratio from CY11 to CY19. The reserve-component population and the National
Guard population showed no interpretable per-year increases in their rate ratios from CY11 to
CY19.

Comparison of Military Suicide Mortality Rates to the U.S. Adult Population
All changes observed in suicide mortality rates for the military populations for CY11-CY18 were
consistent with the increase in the suicide mortality rate for the U.S. adult population over the
same time frame. The comparison only extends through CY18 because CY19 data were not yet
available for the U.S. population.

DoDSER Active Component Data Summary
    •   Firearm use was the most common method of injury cited in suicide DoDSER forms,
        accounting for 59.9% of all CY19 suicides.
    •   Drug and/or alcohol overdose was the most common method of attempted suicide cited in
        DoDSER forms, accounting for 53.1% of reported CY19 suicide attempts.
    •   Less than half (43.6%) of those who died by suicide in CY19 had a documented
        behavioral health diagnosis.
    •   Regardless of whether or not an individual voluntarily disclosed – or was assessed for –
        suicidal thoughts, feelings, or behaviors, approximately half (52.4%) of all individuals
        who died by suicide in CY19 made contact with the Military Health System (MHS) in the
        90 days prior to death.
    •   The prevalence of various risk factors, protective factors, and other suicide event
        characteristics among suicide and suicide-attempt DoDSER forms in CY19 were
        generally consistent with levels observed for previous years.

DoDSER Reserve Component Data Summary
    •   Firearm use was the most common method of injury cited in CY19 suicide DoDSER
        forms for the Reserve (67.9%) and the National Guard (72.7%).
    •   Drug and/or alcohol overdose was the most common method of attempted suicide cited in
        CY19 DoDSER forms, accounting for 46.6% of reported suicide attempts for the Reserve
        and 44.8% of attempts for the National Guard.

                                           Chapter 1: Introduction
The Department of Defense Suicide Event Report (DoDSER) is the official reporting system for
suicide events in the U.S. Air Force, Army, Marine Corps, Navy, and Space Force.1 All cases of
suicide death and suicide attempt among military Service members are to be reported via the
DoDSER.2 The Psychological Health Center of Excellence (PHCoE), a division of the Defense
Health Agency Research and Development (J-9) Directorate, is responsible for the operation of
the DoDSER, which has three primary elements:

    1. A web-based system for collecting, organizing, and securing a standard set of case-level
       data for every service member who dies by suicide or makes a suicide attempt, regardless
       of military service, component, or duty status. The portal for the system is
       https://dodser.t2.health.mil/.1

    2. A data-collection form that guides trained Military Health System (MHS) or command-
       level appointees on the data to assess and collect, as well as potential sources for required
       information. The content of the DoDSER form resulted from a collaborative process
       between the Military Services, civilian and military experts, senior military leaders, and
       key stakeholders. The form is periodically revised to reflect the evolving needs of each
       service; it currently contains more than 500 data elements. Table 1 displays the DoDSER
       form’s content areas.
               Table 1. DoDSER form content areas

                          Content Area                            Variables and Types of Variables

                Military Information                Job code, duty status, permanent duty station
                Event Information                   Access to firearms, event method, event setting
                Medical History                     Behavioral health and medical history

                Narrative Summary                   Information on data-collection strategy

    3. An annual report of aggregated results generated from the data collected during a given
       calendar year. It is the culmination of collaborative efforts between PHCoE, the Suicide
       Prevention Program Offices of the Air Force, Army, Marine Corps, and Navy, the
       National Guard Bureau, the Defense Suicide Prevention Office, and the Armed Forces
       Medical Examiner System (AFMES).

To distinguish between these elements, the words system, form, or annual report appear after the
DoDSER acronym throughout this report.

Interpretation of DoDSER Data
The reader is advised that this annual report’s descriptions of specific risk and contextual factors
must not be interpreted as underlying causes of suicide. It is not possible to determine whether
any variable is a risk factor for suicide solely from the data presented in this report. Identifying
such relationships requires formal research that includes individuals who do not die by suicide or

engage in a suicide attempt. This type of research is outside the surveillance function of the
DoDSER system.

The reader should also take into account the content area of any given DoDSER item when
interpreting results. While this report reflects the best data available, several items address
contextual factors that may not be precisely determined using data from existing databases or
from evidence collected following the event. As a result, these types of items include response
options of “No Known History” and/or “Cannot Determine.” In this report, these response
options are combined with “No” responses to differentiate them from “Yes” responses that
indicate the existence of validating data or evidence. See Appendix B for more information about
DoDSER data processes.

Special Note about the U.S. Space Force
The U.S. Space Force was established on December 20, 2019 within the Department of the U.S.
Air Force. Given the date of establishment, the Space Force data for CY19 will be discussed in
the Air Force chapter of this Report (see Chapter 4). All future DoDSER Annual Reports will
have a chapter dedicated to the Space Force.

Suicide Mortality Rates                                                Calendar Year 2019 Annual Report

                            Chapter 2: Suicide Mortality Rates
This chapter first presents a primer on interpreting statistical data, which includes information
about suicide mortality rate comparisons and a statistical measure of uncertainty, the confidence
interval. The chapter then presents suicide mortality rate data for CY19 and the results of trend
analyses of suicide mortality rates from CY11 through CY19. The chapter also presents results
of comparisons between military and U.S. adult population rates for CY11 through CY18. For
detailed information about the calculation of suicide rates, see Appendix C.

A Primer on Interpreting Statistical Data
Annual suicide mortality rates represent the number of deaths by suicide per 100,000 individuals
from a specified population for a specified year. For example, a rate of 20 per 100,000
individuals means that 20 suicide deaths occurred for every 100,000 individuals in the
population.

Suicide mortality rates can be compared 1) between different populations during the same time
period or 2) within the same population over different time periods. Before undertaking any rate
comparison, one must consider whether the populations differed from one another in a way that
could make a comparison misleading. For example, men have a higher suicide mortality rate than
women in the U.S. adult population and the U.S. military population has a higher proportion of
men than women. A direct comparison of the suicide mortality rates between these populations
would show that the U.S. military rate is higher. This rate difference can be attributed, at least in
part, to the unequal proportions of men in each population. Rate standardization is one technique
that can be used to remove important imbalances between populations. Appendix C provides
more detail on how rate standardization can be accomplished.

Suicide mortality rates and comparisons between them are considered estimates. It is not possible
to know the true values of rates or differences between rates. However, the data collected (i.e.,
observed data) provide the best estimate of the difference. The observed data are used to estimate
a confidence interval (CI). A CI defines a range of values that may contain the true value. A 95%
CI is an interval that has a 95% probability of containing the true value. The estimated value
from the data is considered consistent with a true value contained within the interval, including
the endpoints.1

As an example, if the annual suicide mortality rate for population A was 21 per 100,000 for year
X and for population B was 18 per 100,000 for year X, then the corresponding rate ratio is
21/18=1.17. This means that the observed rate for population A was 17% greater than the
observed rate for population B. The 95% CI for this comparison covers all values from 0.96 to
1.42. This means that the estimated ratio of 1.17 is consistent with a true ratio between 0.96 (or
population A’s rate as 4% less than population B’s rate) and 1.42 (or population A’s rate as 42%
greater than population B’s rate). Note that for rate ratios, a value of 1 indicates that there is no
difference between the rates compared (e.g., 21/21=1). Accordingly, when a confidence interval
for a rate ratio covers the value of 1, the observed data are consistent with a true value of 1 (i.e.,
no real difference between the rates).

CY19 Suicide Mortality Rates by Military Population
Table 2 displays suicide mortality counts and rates by military population for CY19. Tables 3-9
provide suicide mortality counts and rates across demographic categories for each military
population (active component, Reserve, National Guard) and for the active-component
populations of each service. Per DoD policy, suicide mortality rates are not reported for
populations with fewer than 20 events.2

Suicide Mortality Rates over Time

Longer-Term Trends in Rates
The age- and sex-adjusted annual suicide mortality rates for the active component, Reserve, and
National Guard populations from CY11-CY19 are displayed in Figure 1. Similar graphs for the
active-component population of each of the Military Services are displayed in Figure 2. The
dashed line for each graph is the estimated rate from the linear trend assessment.

Table 10 displays the per-year rate ratios and associated 95% CIs from CY11 through CY19 for
each of the populations (see Primer at the beginning of the chapter for an explanation of CIs).
The per-year increases for the total active component population, and the active-component
populations of the Air Force, Marine Corps, and Navy were consistent with true increases. In
contrast, the ratios for the active-component Army population, Reserve, and National Guard
populations were consistent with no true increases.

                 aPer-year rate ratio adjusted for age and sex. Ratios greater than 1 indicate a per-year

                 increase in the associated suicide mortality rate.
                 bThe 95% confidence interval (CI) indicates the range of plausible values for the true

                 ratio. Note that when a confidence interval for a rate ratio covers the value of 1, the
                 observed data are consistent with a true value of 1 (i.e., no real difference between the
                 rates).

Comparison of U.S. Military Suicide Mortality Rates to the U.S. Adult Population
CY19 suicide mortality data for the U.S. population was not available at the time of this report.
As a result, data analyses did not extend beyond CY18. The U.S. suicide mortality rates from
CY11 to CY18 were restricted to the rates for adults aged 17-59 years and then used for analyses
in this report. The age restriction was needed to make the military and U.S. populations more
comparable. From CY11 through CY18, the U.S. adult population suicide mortality rate
increased 2% per year.3

Figure 3 displays the annual standardized rates for the active component, Reserve, and National

Table 11 displays the unstandardized and age- and sex-standardized per-year change estimates
for the active component (total and by service), Reserve, and National Guard populations. After
standardization and accounting for the increase over time in the U.S. adult population suicide
mortality rate, the increases in the suicide mortality rates for the military populations from
CY11-CY18 were shown to be consistent with the increase that occurred in the U.S. adult
population rate over the same time frame.

                     Chapter 3: DoDSER Summary - Joint Forces
Introduction
This chapter presents an overview of the combined Air Force, Army, Marine Corps, and Navy
data for submitted active-component suicide and suicide-attempt DoDSER forms. The data
tables for suicide and suicide attempt cases are presented separately. Data tables are organized by
the following variable categories: demographic and military characteristics (Tables 12 and 13),
suicide event characteristics (Tables 14 and 15), physical and mental health characteristics
(Tables 16 and 17), and psychosocial and adverse experiences (Tables 18 and 19). Data tables
contain joint data as well as data for each of the Military Services. Variables of particular interest
are presented in the text of this chapter and the following four service-specific chapters.

Suicide Mortality
There were 287 active-component suicide deaths confirmed by AFMES for CY19 as of January
31, 2020, all of which required a DoDSER form submission. For inclusion in this report, a
DoDSER form for each event must have been submitted by March 31, 2020. A total of 284 of
the required forms were submitted and three were not. There were an additional 57 events
identified by AFMES as either a confirmed suicide or that were still pending confirmation after
January 31, 2020. No forms were required for submission for these events prior to the cutoff date
for this report; however, any forms submitted were included in the analysis here. We received a
total of 35 of these forms, which brought the total forms available for this report to 319.

Suicide Attempts
Over the course of CY19, DoDSER forms were submitted for 1,462 suicide attempts by 1,388
unique individuals. Note that some individuals made more than one suicide attempt during
CY19.

Occurrence of Previous Suicide Attempt(s) Reported via the DoDSER System
Four active-component CY19 suicides were associated with one or more previously reported
suicide attempt(s) that occurred between CY10 (when attempts were first entered into the
DoDSER system; CY08 for Army) and CY19.

Thirty-three individuals with a submitted CY19 suicide-attempt DoDSER form had one or more
previous suicide attempt(s) recorded in the DoDSER system since CY10 (CY08 for Army). The
median number of days between the first reported suicide attempt in CY19 and the most recent
attempt prior to CY19 was 226 days.

Demographic Characteristics
Demographic characteristics are presented in Tables 12 and 13. The demographic profiles for
both suicide and suicide-attempt DoDSER forms were consistent between CY19 and the
averages for CY16-CY18. Note that the three-year averages for CY16-CY18 were used to
provide more stable statistical comparisons.

Method of Injury
Firearm use was the most common (59.9%) method of injury identified in suicide DoDSER
forms. This was consistent with the average percentage for CY16-CY18. The majority (87.4%)
of the firearms used were personal possessions. Relatively few firearm deaths (9.9%) resulted
from the self-directed use of a military-issued firearm. For suicide-attempt DoDSER forms, drug
and/or alcohol overdose was the most frequently reported method of injury (53.0%). This
indicated a 6.1% reduction (95% CI = -11.3%, -0.6%) in attempts attributable to drug and/or
alcohol overdose relative to the average for CY16-CY18.

Behavioral Health History
Among suicide DoDSER forms, 43.6% had at least one current or past behavioral health
diagnosis in their medical record. Substance use disorders (20.7%) and adjustment and mood
disorders (17.9% each) were the most common diagnostic categories. Among suicide-attempt
DoDSER forms, 57.3% had at least one current or past behavioral health diagnosis in their
medical record. Mood disorders (29.7%), substance use disorders (21.6%), and anxiety disorders
(21.5%) were the most common diagnostic categories.

Figure 5 displays the prevalence of mental health diagnoses, prior self-harm, and the use of
psychotropic medication in the 90 days prior to a suicidal behavior among active-component
DoDSER forms submitted for CY19 and the three-year average for CY16-CY18. The prevalence
estimates from CY19 suicide and suicide-attempt DoDSER forms were largely consistent with
the average estimates for CY16-CY18. For suicide-attempt DoDSER forms, there was a 13.1%
reduction (95% CI = -21.5%, -3.7%) in the prevalence of recent psychotropic medication usage
relative to the average for CY16-CY18.

type, CY16-CY19. Blue bars represent CY19 data, black bars are the three-year averages for CY16-CY18, and the
whiskers are the half-width of the 95% confidence intervals.

Health Care Utilization

Regardless of whether or not an individual voluntarily disclosed – or was assessed for – suicidal
thoughts, feelings, or behaviors, 52.4% of the Service members who died by suicide in CY19

had been in contact with the MHS in the 90 days prior to death. The most common type of
appointment was a general visit to a medical treatment facility (45.8%) and the second most
common type was a mental health visit (32.0%). Outpatient mental health services were utilized
in 31.3% of cases while inpatient mental health services were utilized in 6.3% of cases.

For reported suicide attempts, 61.7% of the DoDSER forms indicated contact with the MHS in
the 90 days prior to the behavior. The most common types of appointments were general visits to
a medical treatment facility (50.4%) and mental health visits (47.2%). Outpatient mental health
services were utilized in 45.1% of cases while inpatient mental health services were utilized in
14.7% of cases.

Stressors
Among suicide DoDSER forms, relationship (42.6%), legal/administrative (28.5%), and work
(13.8%) stressors within 90 days of the event were the most common stressors identified in
CY19 (Figure 6). Similarly, among suicide-attempt DoDSER forms, relationship (36.7%),
legal/administrative (28.7%), and work (35.0%) stressors were the most common stressors
identified in CY19 (Figure 6). The prevalence estimates from CY19 suicide and suicide-attempt
DoDSER forms were largely consistent with the average estimates for CY16-CY18. For suicide
DoDSER forms, there was a 31.8% reduction (95% CI = -49.6%, -7.5%) in the prevalence of
work stressors relative to the average for CY16-CY18.
